Would it be worse to make the icon invisible instead of inactive?
Second question is if it would be possible to right-align the icon
(instead of left-aligning it, where it makes reading a bit more
difficult).

Basically, balloon help for input errors.

It could be that this appeared only when a certain time had passed
(though the input would still be considered invalid) or if focus left
the input area.
But I have come to generally think that multiple mechanisms for
different types of validation errors are the way to go; that implies
having a [small] set of forms of feedback implemented in a library.

We do this in some of our interfaces; it works well but requires you to
design this in up-front.

Interesting, will take a look.
Take care,
